The box is made out of conductive plastics.

The fan has a backward- curved radial impeller made out of powder-coated steel plate.

The actuation is carried out by an explosion- proofed, speed-controllable external rotor motor with PTC.

For annealing the motor is situated inside the air flow.

Motor completely with impeller statically and dynamically weigh heavy according to DIN ISO 1940.

Tested according to ATEX- Guideline 2014/34/EU.

For the extraction of potentially explosive atmosphere of zone 1, category 2G and zone 2, category 3G.

Field of application for gases of groups IIA, IIB and hydrogen.

Clasification: II 2G Ex h IIB+H2 T3 Gb

Appurtenances for the Ex- fan is available on enquiry.

ATEX-approval number TPS 20 ATEX 085751 0009 X.
